Webendo-BCN-PEG3-NHS esterr can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The BCN group enable copper free click chemistry with azide-tagged biomolecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. WebBriefly, TCO derivative 3 was modified with bis-2- (trimethylsilyl)ethyl aspartate to give intermediate 8, and the allylic alcohol group was converted to the p -nitrophenyl (PNP) carbonate 9. ETP-TCO-asp was obtained by coupling of 9 with ETP and subsequent deprotection of the bis- (trimethylsilyl)ethyl ester groups using TBAF.

Web4-Nitrophenol is an intermediate in the synthesis of paracetamol. It is reduced to 4-aminophenol, then acetylated with acetic anhydride. [6] 4-Nitrophenol is used as the precursor for the preparation of phenetidine and acetophenetidine, indicators, and raw materials for fungicides. Bioaccumulation of this compound rarely occurs. 4-Nitrophenol can be used as a pH indicator. A solution of 4-nitrophenol appears colorless below pH 5.4 and yellow above pH 7.5. This color-changing property makes this compound useful as a pH indicator. The yellow color of the 4-nitrophenolate form (or 4-nitrophenoxide) is due to a maximum of absorbance at 405 nm (ε = 18.3 to 18.4 mM cm in strong alkali). In contrast, 4-nitrophenol has a weak absorbance at 405 nm (ε = 0.2 mM cm ). The isosbestic point for 4-nitrop…
